Full Transformers 2 Revenge of the Fallen trailer

Sam Witwicky (Shia LaBeouf) discovers something about the origins of the Transformers and their history on planet Earth. The evil Decepticons need to capture him for new info. The climactic battle takes place at the Giza pyramid complex, where a big temple is located within. Lorenzo di Bonaventura explained the film will show the Transformers who visited Egypt before the pyramids were actually built, and "all our heroes end up here because of the Decepticons' masterplan." Also, Egyptian hieroglyphs resembling helicopters and other present day vehicles in real life will be explained in the film as being depictions of those Ancient Cybertronians who visited Earth.
